Application filed June 21, 1918. Serial No. 241,250.

To all whom it may concern:

Be it known that I, WILLIAM E. WALSH, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Builder Mechanism for Spinning or Winding Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

lhis invention relates to improvements in spinning machines, and more particularly to the builder mechanism employed in such machines for winding yarn on receivers or bobbins to be subsequently used as filling or weft during the weaving of cloth.

In that general type of looms wherein the filling is replenished prior to complete exhaustion of that in the running shuttle, it is usual to provide a reserve supply of filling on the bobbins or other receivers, part, at least, of which will remain upon the bobbin or receivers after the working supply has been substantially exhausted and the feeler mechanism has called for replenishment. Many devices have been devised for placing this reserve supply of filling or bunch as it is, sometimes called, on the bobbins or receivers during the spinning operation, and one of the objects of the present invention is to provide a mechanism for this purpose which shall be simple in construction and effective in operation.

Another important feature of the present invention consists in a builder mechanism which, by manual manipulation, may be set to start the winding of the bunch at any desired point along the length of the bobbins or receivers and upon starting the machine will automatically vary the traverse until the bunch is completed and then insure resumption of regular service traverse commenclng at the base of the bobbln or receiver.

Another feature of importance is the facility with which the attendant may manually adjust the 'mechanism to place the bunch on any desired part of the bobbin or receivers without disassembling or changing the construction. Other features of the invention will best be made clear from the following? description and accompanying drawings which disclose one good practical form of the invention.

in the drawings Figure 1 is a view of a portion of a Worsted spinning machine provided with the present invention;

Fig. 2 is a front viewof the parts, certain portions being broken away for clearness of illustration;

The main supporting frame of the machine may be of any desired construction, and as shown in the present instance, the in vention comprises the end frame, the memhers 1 connected by longitudinally-extending rails 2, 3, the latter of which constitutes a spindle-bearing rail. In the present instance of the invention, it is shown and will be described in connection with a well-known form of worsted spinning machine, but it is to be understood, of course, that it is not confined to such use, and may be advantageously employed in connection with other forms of spinning machines.

Moun ,ed on the spindle rail 3 are the spindles 4 which, as usual in worsted spinning machines, extend upwardly through a wayplate or lifting rail 5. Each of the spindles 4 is adapted to support a yarn receiver or bobbin 6 which extends upwardly into the usual cap 7 Fig. 1, mounted upon the top portion of the respective spindles l or suptraverse slide 22 is a cam lated by the builder cam 10 as usual. In the present instance, the arm 12 has mounted thereon at 13, the roller 14 which bears upon the builder cam 10. Pivotally mounted at the lower portion of the machine frame is the swing arm 15 which may be of usual con struction. Mounted for rising and falling mo ement on the swing arm 15 is the'bracket 16 carrying a roller 17 adapted to bear upon the arm 12, the construction being such that as the swing arm actuator 12 is operated by the builder cam, the swing arm 15 will be actuatedand thev amplitude of its movement will be controlled by the position of the bracket 16 carrying the roller 17. The bracket 16 has connected thereto the rack 18 whichengages a pinion 19 connected to the shaft 20, whereby the position of the bracket 16 may be adjusted during the building operation, as usual in worsted spinning machines. to the swing arm 15 is the traverse screw 21 which transmits traverse motion from the builder mechanism thus far described, to cause relative traverse movement between theyarn receivers and yarn guides or caps.

Suitablysupported for sliding movement on the machine frame is the traverse slide 22 to which is secured a chain 23 or other flexible connection extending between the traverse slide and a block 24 on the lower end portions of the lifter rods 25 which at their upper ends are secured to the wayplate or lifterrail 5. The chain or flexible connection 23 may be conveniently guided between the traverse rail 22 and the lifter rods 25 by the guide pulleys 26. The parts thus far described may be of any .usual or suitable construction, as art,-or as pointed out by the patent to Leonard, No. 1,212,650, dated June 16, 1917.

Mounted for rotary movement on the shaft 27. The traverse slide 22 may have a bearing 28 of sufiicient extent to maintain the cam shaft properly alined in its bearing. Secured to the cam shaft 27 is a cam 29, Figs. 4, 5 and 7, which is adapted to bear against the end of a slide member 30 mounted for sliding movement-in a guide or bracket 31 secured to the traverse slide 22. In the present instance of the invention the guide 31 may have its lower portion formed integral with the traverse slide 22 and be provided with a cap 32 secured to the guide 31 by suitable means such as the screws 38v for holding the sliding member 30 in guiding relation with itsguide, For the purposes of identification the sliding member 30 may be hereinafter 60 designated a plunger, and as shown in the present instance of the invention, it is provided' with an. enlarged head portion 34- against which is seated the end of the tra-verse screw 21;

The plunger Connected to the shaft 20 and alsocommon in the 7 30 is preferably provided.

with a roller 35 at its end opposite thchead 34 which is adapted to bear against the cam 29 carried by the cam shaft 27. From the construction thus far described it will be apparent that should the cam 29 beturned to present different portions thereof to the plunger 30, the traverse rail 22 on which the cam is carried, will be correspondingly shifted or moved since the head 34 of the plunger rests against the end of thetraverse screw 21. V I

Secured to the cam shaft '27 is a ratchet wheel 36 having a series of teeth 37 and a blank space Mounted for rockingmovement on'the cam shaft 27 is ahub 39 having extending therefrom a pawl-carrying arm 40 to which is pivotally connected as at 41, a pawl 42 adapted to coact at times with the ratchet teeth 37 of theratchet 36. Also can tending from the hub 39 is an operating arm 43, to the lower end portion of which is pivctally mounted as at 44, a; sleeve 45; Extending through the sleeve 45 is a rod having connected thereto the stop collars or nuts 47. The rod 46 may be operated from any convenient part of the machine to actuate the pawl, but in the present instance of the invention this rod is extended to and connected with an arm 48 rotating with the builder cam 10,'as indicated in Figs. 1 and 2.

Secured to, the longitudinal rail 2 of the machine is a supporting stand 49 having at its upper portion a guide for directing the movement of the traverse rail 22- and assist in supporting the 'eight of parts carried by the traverse slide. In the present instance ofthe invention, the stand 49 has a slotted guideway 50, Fig. 1, through which passes" the cam shaft 27 which'thereby serves also as a guiding and supporting means for the traverse rail and the parts carried by it.

Connected to the cam shaft 27 is a hand lever 51 adapted at times to be operated by the attendant. In the present instance of the invention, the hand lever or crank 51 is secured to the cam shaft 27 outside the guideway 50, thereby serving also as a steadying means for the traverse rail22 and the parts carried thereby.

Connected to the pawbcarrying arm 40 is a weight 52, Figs. 2 and 5, which normally holds the pawl-carrying arm and its connected parts with the arm 40 resting upon the stop 53 secured to the traverse slide 22 or a; bracket connected therewith, the construction being such that the pawh carrying arm 40 W11] normally tend to rest against the stop 53- in the position indicated nger 54 is-extendedover the pawl 42 to prevent the latter from' in Figs; 2 and 5. A fi mountedthereon, has a weighted end- 58' which normally holds the end of the pawl in engagement with the ratchet teeth 37 and serves to prevent rotary movement of the ratchet wheel 36.

In placing the preliminary windings or a bunch, so-called, upon the yarn receia ers or bobbins, it is desirable to locate the primary windings or bunch at tances from the head of the bobbin in order that it may be properly disposed relative to the feeler mechanism. At the same time, the regular traverse windings placed upoi the receivers or bobbins should start at the base of the bobbin or receivers in order to get the proper amount of yarn thereon. This condition'is true with respect to any yarn receivers or bobbins'used in a feeler loom. and is particularly desirable where the bobbin is of the slotted type. In either event, however, the present invention provides means whereby the attendant may turn the cam 29 into such position relative to the plunger 30 that the preliminary windings or bunch may start to be wound at any point in the longitudinal length of the yarn receiver or bobbin, and be located at any part thereof, and at the same time the service windings may be caused to commence at the lower or head end of the yarn receivers or bobbins.

In the present instance of the invention, the cam 29 i shown as of a character to provide a bunch or preliminary windings substantially like that shown at a on the yarn receiver or bobbin 6, Fig. 3. In forming such bunch, the attendant, before starting the machine, turns the cam shaft 27 by the hand lever or crank 51. to brim the desired 10W part of the cam '29 against the end of the plunger 30, thereby permitting the traverse slide 22 to move perforce lower the way-)late or guide rail 5 and the bobbins or yarn receivers. The point to which the yarn receivers or bobbins will be lowered relative to the fixed caps will obviously depend upon the position or the cam 29; consequently, by properly manipulating the cam, the preliminary windings or bunch may be started at any point of the bobbin or yarn receiver. As hereinbcfore pointed out, it is desirable that the service windings shall commence at the or head of the bobbins. To this end the cam 29 is so formed that when the high part thereof acts against the end of the plunger 30, the traverse slide 22 is moved to the right a sufficient distance to thereby lift the wayplate or guide rail 5 and raise the bobbins relative to the fixed caps to start the service winding at the base or head of the bobbins.

The attendant having set the cam to com- Inence the preliminary or bunch windings at the desired part of the yarn. receivers or bobbins, the machine is started and as the lifter cam rotates, the pawl 42 will be actuated to step the ratchet wheel 36 along and different dis to the left andv thereby rotate the cam 29 until the end of the pawl reaches the toothless portion 38 of the ratchet wheel 36, at which time the preliminary windings or bunch will have been completed and the cam 2-9 reached position to start the service windings at the base of the bobbins or yarn receivers. The preliminary or bunch windings, as will be observed from the above description, commences at the top of the primary or bunch windings and proceeds downwardly, and as layer after layer of the primary or bunch windings is laid, there is an increase of gain downwardly due tothe action of the cam 29; and when the preliminary or bunch windings iavc been completed and the pawl has reached the toothless portion of the ratchet wheel 36. service traverse windings will be started from the base of the bobbin or yarn receivers upwardly.
